About our fire protection for steel beams service in Lisburn
We carry out fire protection for steel beams in Lisburn, covering the BT17, BT27 and BT28 postcode districts. The wider Lisburn and Castlereagh area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We fit fire protection alongside new steelwork, and as a standalone job where steel was installed without it or building control has asked for more. That covers boxing with fire-rated plasterboard, intumescent coatings for steel left on show, and the records building control needs to see before signing the work off.
Key points for your project
- Older homes sometimes have steel fitted decades ago with no protection at all, or boxed in ordinary timber and hardboard. When this turns up during other work, we can check what is there and price protection to suit today's requirements.
- Boxing a single beam usually takes around a day, plus skimming and drying. Intumescent coatings need each coat to dry before the next goes on, so they can take several days depending on the thickness required and the room temperature.
- Building control treats fire protection as part of the structural approval, not an optional extra. If unprotected steel is found at inspection, the completion certificate is normally held back until the protection is in place and has been checked.
- Boxing is generally the lower-cost route for steel that will be hidden. Intumescent coatings cost more because of the product and the number of coats, and the price rises with the fire period and the size of the section.
- Boarding is fairly clean work, but coatings need a clean, dry and well-ventilated room at a suitable temperature. Dust from other trades can spoil the surface, so painting is normally scheduled once the messy work in that room is finished.

Approvals in Lisburn
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Lisburn that is Lisburn and Castlereagh City Council. We submit a full plans application or building notice before work starts and book the inspections.
Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

Questions about fire protection for steel beams in Lisburn
Can I stay at home while the work is done in Lisburn?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How much does fire protection for steel beams cost in Lisburn?
As a guide, budget £130–£520 per beam including VAT for fire protection to a steel beam in Lisburn, based on published UK cost guides adjusted for prices in Northern Ireland (-14%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Does a steel beam in a house need fire protection?
Usually, yes. Where a steel beam or column holds up part of the structure, building regulations normally require it to resist fire for a set period, commonly 30 minutes in a typical house. Building control confirms what is needed for your property, and the protection is checked before the work is signed off.
What is intumescent paint for steel beams?
Intumescent paint is a fire-protective coating that swells when heated, forming a thick insulating layer that slows the steel heating up. It lets you leave a beam on show while still meeting fire requirements. It must be applied at a specified thickness over a compatible primer, so it goes on to a written specification rather than like ordinary paint.
Can I put downlights in a boxed-in steel beam?
Only with planning. Cutting holes in fire boarding can weaken its protection, so any lights in or near the boxing need to be designed in, using fire-rated fittings or suitable fire-stopping where the board is pierced. It is far easier to sort this out before the boxing goes up than to adapt it afterwards.

Yes. We also cover nearby towns including Castlereagh, Newtownabbey, Newtownards and Craigavon.
